I wanted it to have an antique drawing look to it, so I printed the drawings on an ivory cardstock. I used my scalloped shears around the edges which gives it an almost postage stamp appearance. I then centered and mounted it on a black 12x12" scrapbook cardstock to give it a gallery look.
Lastly, I centered them on the wall and hung them about 2-3" apart. I then cut 4" pieces of yarn (twine or sisal rope, or small chains would look neat too) and taped them to the backs of the frames to "hitch" the train cars together.
A super easy, fast, and budget friendly project that just looks soooo cool in his room. I hung it above the train table in his room and he LOVES it! It's gives his room a more "big boy" feel and is even nice enough to display in a family room.
